Answer:

-7

Step-by-step explanation:

Let's put this into an equation with x being the unknown number. Then use the reversed order of operations to find the value of x.

x + -2 = -9

   + 2   + 2

x = -7

Answer:

x=-7

Step-by-step explanation:

Translate into an equation.

“A number” + -2 = -9

Assign “a number” to be “x”

X+-2=-9

Add 2 on both sides to even it out and get x

X-2+2=-9+2

X=-7

The number is -7. :)

How do you find the slope of a line?<br><br> (Change in Y / Change in X)
sukhopar [10]
In order to find the slope of a line, u must use the slope formula. Which is (y2-y1/x2-x1). For example if you had a set of coordinates that are (6,4) and (2,8) you would first sub the 8 from4 which gives you 4. The u do the same with 2 and 6 which gives u 4. After that you divide 4 by 4. and your answer is 1

Let f(x) = 6x^2 + 5 and g(x) = 3x - 5. Find f(g(7)).
Vedmedyk [2.9K]

Answer:

D) 1541

Step-by-step explanation:

I like to answer it w without deriving the formula of f(g(x)). So, we go this way, you firstly have to find g(7) which will be equal to 3 * 7 - 5 = 16.

And then you find f(16) = 6*16*16+5 = 1541. That's all.

One taxi leaves at a stop at every 6 minutes a second taxi leaves the stop every 9 minutes if they leave at 4.00 p.m at what tim
qaws [65]

Both taxis will leave together at 04:18 PM after 04:00 PM

Step-by-step explanation:

We have to use the LCM to find the time on which both will leave at the same time,

Given

Departure interval for first taxi = 6 minutes

Departure interval for second taxi = 9 minutes

We have to find the LCM of 9 and 6

So,

Factors of 6: 6,12,<u>18</u>,24,30,36,42,48,54,60

Factors of 9: 9,<u>18</u>,27,36,45,54,63,72

The LCM is 18.

So,

Both taxis will leave together at 04:18 PM after 04:00 PM
